JAMES W'. TAYLOR, OF SHKOSH, WISCONSIN. Leitersliahnt No. 69,044, dated September 17, 1867.

IMPROVEMENT IN SHAFT-COUPLING.

TO ALL WIIOM IT MAY CONCEBN: i

Be it known that I, JAMEs W. TAYLOR, of the city of Oshkosh, county of Winnebago, and State of Wisconsin, have invented a new and improved Device for Coupling Shafting whenV 'theshafting is required to be placed in an oblique position relatively to each other, and known to the art as a knuckle-joint ora` universal joint. i l i l VThe object of this invention is to provide a simple and direct mode for the purposes specified, that, while it works free and easy, is compact and secure, and by having the workings of the coupling encased in a cylinder avoid the possibility ofcatching the clothes of attendants incident to the eoupling'of tumbling-rods of threshing machines and of other shafting of like dangerous character.

I hereby declare that the following is a full, clear, and exact description ofthe construction and operation of the saine, reference being had 'to the annexed drawings, making a part of this specification, in which;-

Figures 1 and 2 are perspective views of the respective parts. l

Figure 3 is a longitudinal sectionoil iig. `1.

Figure 4 is a longitudinal and Figure 7 is a vertical section of fig. 2, seen at o o and n n, fig. 5.

Figure 5 represents figs. l and 2 partially adjusted for service. l

Figure 6 is a pair of.irregular-shaped friction-rollers, seen at e c, fig. 1.

A is an outer end View of g. 1. C isan outer end view of iig. 2, A and C each having mortises it', in which the\shafting is to be inserted. a is a hollow cylinder with a head in one end. The' inne-r periphery of the opposite end of the cylinder is rounded out to near the outerv periphery of tho cylinder. ce are duplicate friction-rollers-independent in their action; are bevelled on one end and roundedon theouter. end. v They are provided with hubs or collars, (seen in iig. 6,) and are used together on one shaft, the hcv'clled ends facing, learing an opening vbetween bovels similar to that of a spool, and are inserted crosswise in the centre of the open end of the cylinder a., c is an irregular cylindrical form. Its diameter is somewhat smaller" than' the inner diameter of cylinder a.. One end is slotted, leavihg astubbed forked head, seenin iig'. 2. The inner edges of the prongs are bevelled, as seen in fig. 7,-to fit the friction-rollers. Fig. 2 is in-sertedin iig. 1, as seen in iig. 5,

and when fully inserted is adjusted for service. p

My invention consists in providing a hollow metallic cylinder with a'pair of friction-rollers, spool-like in; form, when used together, each roller or spool end working independently on a common shaft, andthe whole inserted crosswisc in the opejn end of the cylinder. Used Iin conjunction with the above is a circular metallic" head, with two prongs of a size and shape for easy oblique working in and corresponding to the openings in the said cylinder, remaining between the friction-rollers and the, inner periphery ofthe cylinder. The two parts complete the knuckle-joint.

What I` claim as my invention, .and desire to secure by Letters Patent, is Y The hollow cylinder a provided with friction-rollers e a, substantially ns described, when used in combina; tion with the dual pronged head chas and for the purposes set forth.
